What Plasma Dilution is
The mouse experiment that asked whether young blood is necessary at all. Replacing half the plasma with saline plus albumin, adding nothing young, matched the effects attributed to young blood.
Everything in the young-blood field assumes that something in young plasma is doing the work. Plasma dilution is the control experiment for that assumption.
Mechanism: Established in mice only. The proposal is that plasma contains autoregulatory proteins whose concentrations feed back on their own production and on multiple signalling pathways, so that diluting them resets those pathways and produces durable transcriptional changes rather than a transient concentration drop.
Regulatory history: Not approved anywhere as an ageing intervention, and not registered as a human trial under this name. The closely related human procedure, therapeutic plasma exchange, is an established medical treatment with its own indications.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for Plasma Dilution at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
